Well submersible pump capable of cleaning impurities adhered to filter screen and preventing blockage

The well submersible pump comprises a submersible pump body and a filter assembly, a water outlet is formed in the top end of the submersible pump body, a plurality of connecting rings are arranged on the outer side of the water outlet, a water inlet is formed in the bottom end of the submersible pump body, and the filter assembly is arranged on the outer side of the water inlet. The well submersible pump capable of cleaning the impurities adhered to the filter screen and preventing blockage is reasonable in structure, can filter the impurities during operation of the well submersible pump, reduces the impurities entering the well submersible pump, avoids influence on operation of the well submersible pump and damage to the internal structure of the well submersible pump, and is high in practicability. According to the well submersible pump, impurities on the outer side of the filtering device can be cleaned, the situation that the filtering device is blocked, and the water pumping efficiency of the well subm
